Abstract:
PURPOSE: A method for biological control of plant diseases using Chaetomium globosum F0142 and chaetoviridins A and B produced by the same is provided, thereby effectively controlling plant diseases. CONSTITUTION: A method for biological control of plant diseases using Chaetomium globosum F0142(KCTC 0957BP) and chaetoviridins A and B produced by the same comprises spraying the cultured medium, mycelia or spores of Chaetomium globosum F0142, or chaetoviridins A and B isolated from the Chaetomium globosum cultured medium to plants, wherein the plant disease is rice blast disease, late blight, leaf rust or phytophthora blight. The chaetoviridins A and B are represented by the formula(1) and (2) respectively, and purified by extraction of Chaetomium globosum F0142(KCTC 0957BP) with ethyl acetate, first silica gel column chromatography, thin layer chromatography and second silica gel column chromatography, sequentially.

Abstract:
PURPOSE: Provided are novel propanoic ester and amide derivatives having an oxime group as a branched chain, which are excellent in disinfecting activity, a preparation thereof, and a disinfectant composition containing the propanoic ester and amide derivatives. CONSTITUTION: The propaonic ester and amide derivatives represented by the formula 1 are produced by a process comprising the steps of: reacting a bromine compound represented by the formula 2 and 2,3-butanedione monoxime represented by the formula 3 in the presence of a base to produce an oxime-based ketone compound; reducing the oxime-based ketone compound or condensing the oxime-based ketone compound with a hydroxyl amine to produce an oxime-based alcohol compound or a dioxime-based compound; reacting the oxime-based alcohol compound or the dioxime-based compound with a propanyl fluoride compound in the presence of a base. In the formula, R1 is trifluoromethyl, R2 is a phenyl group, X is CH or N, and Y is O or NH.
Abstract:
PURPOSE: Provided are Stenotrophomonas maltophilia A-2 (KCTC 0659 BP) and 51-4 (KCTC 0658 BP) which biologically decompose aniline and its derivatives contaminating soil, underground water, stream, pond or waste water. CONSTITUTION: Stenotrophomonas maltophilia A-2 (KCTC 0659 BP) or 51-4 (KCTC 0658 BP) is obtained by the following steps of: i) cultivating water sample from a stream at minimum medium containing aniline at 30 deg.C at 200rpm for seven days; ii) checking if aniline is decomposed on the medium; iii) inoculating the broth into PTYG agar plate containing 300μg/ml of aniline and separating purely colonies; and iv) cultivating the colonies in broth containing aniline. The two strains purified here are all gram-negative. And the bacteria decompose aniline between pH 5.0-9.0, preferably pH 6.0-8.0, most preferably pH 7.0.
Abstract:
PURPOSE: An Acremonium strictum strain, hyperparasite of Botrytis cinerea and a method for inhibiting diseases caused by Botrytis cinerea using the same are provided for substituting chemical insecticides with biological insecticides, so that they do not cause the contamination of nature. CONSTITUTION: Acremonium strictum BCP strain (KCTC 0639BP) is hyperparasite of Botrytis cinerea and is useful in inhibiting and treating the diseases caused by Botrytis cinerea. All plants, which may be infected by Botrytis cinerea, such as cucumber and tomato, may be treated with Acremonium strictum BCP strain (KCTC 0639BP) in an effective amount so as to inhibit plant diseases, in which the amount of Acremonium strictum BCP strain (KCTC 0639BP) is in the range of 1x104 to 3x108 spores/ml, preferably 1x106 to 3x107 spores/ml.
